Wild tales about flying saucers at Nevada's mysterious Area 51 military base are, by now, familiar all over the world. Those stories started on KLAS-TV back in 1989 and have since been featured in movies, TV shows and books.

Two new books explore how the story has evolved over the past 24 years and whether there is any truth to the claims of former government scientist Bob Lazar, who says he worked near the secret base at Groom Lake.
